> is EXA a one-for-one replacement for XAA, or just for some use cases?

EXA is designed for modern compositing environments, whereas XAA is
excessively optimized for every little bit of core X11 rendering operations
and hasn't really evolved much this millenium. So while EXA should be on par
or faster with modern applications (especially with a compositing manager,
even just xcompmgr -a) it'll probably never be able to match XAA in all
cases with older applications, at least not without turning into the same
kind of monster.
